4 Claims. (Cl. 12S-58) This invention relates to massaging devices, and more particularly to a spinal massager. i

An object of this invention is to provide a massaging machine which is particularly designed for massaging the spine and which is formed of two or more rubber rollers which are mounted in a position to have rolling and moving contact with the spine of a person reclining on top of the machine.

Another object of this invention is to provide a spinal massaging machine which can be easily adjusted to provide for the desired massaging action.

A further object of this invention is to provide a spinal massaging machine which is simple in construction and will give the desired massaging action.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings- Figure l is a longitudinal section of a spinal massaging machine constructed according to an embodiment of this invention,

Figure 2 is a plan view, partly broken away, of the device with the top removed,

Figure 3 is a sectional View taken on the line 3 3 of Figure 1,

Figure 4 is a fragmentary sectional view taken on the line 4 4 of Figure 2,

Figure 5 is a fragmentary sectional view taken on the line 5 5 of Figure 2,

Figure 6 is a fragmentary sectional view taken on the line 6 6 of Figure 3,

Figure 7 is a sectional view similar to Figure 3, showing a modified form of this invention,

Figure 8 is a fragmentary sectional view taken on the line 8 8 of Figure 7.

Referring to the drawings, the numeral 10 designates generally a cabinet which is formed of opposite side walls 11 and 12, and opposite end walls 13 and 14. A top 15 is disposed on the upper edges of the side and end walls and is formed with an elongated rectangular opening 16.

A horizontally disposed roller carrying frame generally designated as 17 is mounted in the cabinet 10 below the top 15. The frame 17 is formed of a pair of longitudinal frame bars 18 and opposite end bars 19 and 20. A pair of shafts 21 and 22 are journalled across the frame 17, being mounted in bearings 23 and 24 respectively.

Shaft 21 has secured thereto a pair of sprockets 25 and shaft 22 has secured thereto a pair of sprockets 26. A pair of endless chains 27 are engaged about the sprockets 25 and 26 and a pair of rubber rollers 28 which are mounted on shafts 29 journalled in V-shaped bearing brackets 30 are secured to the chains 27 and extend therebetween. The rollers 28 are adapted on the upper runs of the chains 27 to project partly through the opening 16 in the top wall for rolling contact with the spine of a person reclining or otherwise disposed on the top 15.

A pair of downwardly inclined frame bars 31 are secured at their upper ends to the frame 17 between the ends of the latter, and the lower ends of the bars 31 are rockably mounted on a horizontal transverse shaft 32 which is mounted at the opposite ends thereof in bearings 33 secured to the inner sides of the side walls 11 and 12.

The bars 31 have secured to the upper sides thereof a plate 34 on which a motor or power member 35 is mounted, and a speed reducing means 36 of conventional constructionis connected with the power member 35 and includes a shaft 37 having a sprocket 38 mounted thereon. A chain 39 is engaged about the sprocket 38 and is also engaged about an upper sprocket 40 which is mounted on the shaft 22.

In order to provide a means whereby the roller frame 17 may be vertically adjusted and maintained in a horizontal position, I have provided a cross shaft 41 mounted in bearings 42 secured to the inner sides of the side walls 11 and 12, and the shaft 41 has secured thereto a pair of upwardly projecting arms 43. The inner end of the roller frame 17 has depending therefrom a pair of arms or levers 44 and the anns or levers 44 are pivotally connected to a pair of pivoted links or levers 45 which are pivotally secured between the arms 43 and 44. The arms or levers 45 are pivotally secured between the ends thereof, as at 46, to downwardly inclined bars 31.

A screw shaft 47 is journalled in a' bearing 48 carried by end wall 14 and is also journalled in a transverse bar 49 secured between the sides 11 and 12. A hand wheel 50 is secured to the outer end of shaft 47 whereby the latter may be rotated to vertically adjust the frame 17.*,

Referring now to Figures 7 and 8, the numeral 10a designates generally a cabinet similar to cabinet 10, and the cabinet 10a has mounted therein a roller carrying frame 17a which is similar to the frame 17. In the present instance the frame 10a is vertically adjusted as, will be hereinafter described. V A

A horizontal shaft 53 is rockably mounted in bearings 54 secured to the sides of the cabinet 10a, and the shaft 53 has fixed thereto a pair of spaced apart arms 55. A pair of links 56 are pivotally secured at their lower ends to the arms and are pivotally secured at their upper ends to the frame 17a. The shaft 53 also has fixed thereto a pair of depending lever arms 57 which are disposed at substantially right angles to the arms 55 and are positioned inwardly from the latter.

A screw shaft 58 is journalled through a bearing 59 carried by one end of the cabinet 10a and is journalled at its inner end through a horizontally disposed angle bar 60 which is fixed between the sides of the cabinet 10a. A nut 61 is threaded on the shaft 58, and a pair of longitudinally bent links 62 are pivotally secured at their forward ends to the nut 61 and are pivotally secured at their inner ends to the depending lever arms 57.

The screw shaft 58 has fixed to the outer end thereof a hand wheel 63 so that the shaft 58 may be rotated to rock shaft 53 and thereby raise or lower the roller frame 17a. In other respects the structure shown in Figures 7 and 8 is identical with the structure shown in Figures l to 6 inclusive.

In the use and operation of this device, the rollers 28 are adjusted by turning of the hand wheel 50 and the screw shaft 47 so that the rollers 28 will project on the upper runs of the chains 27 through the opening 16 for a desired distance. Power member 35 is operated so as to move the chains 27 and as the rollers 28 move lengthwise along the upper runs of the chains 27, these rollers will have rolling and moving contact with the body of the person reclining or otherwise disposed on the top or table 1 5.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.
